Underscore.js _.bound() Method

Last Updated : 19 Aug, 2020

The _.bound() method returns function which is a property of an object by name, bound to the object made.

Syntax:

_.bound( obj, function);

Parameters:

obj: The object in which the function is defined.
function: A function defined containing the returning logic.

Return Value: This method returns a function.

Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed. Underscore.js contrib library can be installed using npm install underscore-contrib –save.

Example 1:

JavaScript

// Defining underscore contrib variable
var _ = require('underscore-contrib'); 

var gfgObject = {
    name: "GeeksforGeeks",
    detail: "Computer science portal for geeks",
    geekFunc: function() {
        return this.name + ": " + this.detail;
    }
};

var gfgFunction = _.bound(gfgObject, "geekFunc");
console.log(gfgFunction());

Output:

GeeksforGeeks: Computer science portal for geeks

Example 2:

JavaScript

// Defining underscore contrib variable
var _ = require('underscore-contrib'); 

var gfgObject = {
    one : 1,
    two : 2,
    geekFunc: function() {
        return this.one + " and " + this.two;
    }
};

var gfgFunction = _.bound(gfgObject, "geekFunc");
console.log(gfgFunction());

Output:

1 and 2
